Information processing method and device

Abstract

Embodiments of the present invention provide an information processing method, applied to an electronic device including an image acquisition unit. The method includes acquiring depth information of an image captured by the image acquisition unit; based on the depth information and the captured image The power of the fill light unit used in the image affects the exposure of pixels at different depths in the image, and the correction coefficients corresponding to the pixels at different depths are calculated; the initial pixel values ​​of all pixels are corrected using the correction coefficients, and according to The resulting corrected pixel values ​​for each pixel generate pixel restored values ​​for each pixel in the image.

Description

technical field [0001] The present invention relates to an information processing method and device, more specifically, the present invention relates to an information processing method and device for performing different restoration corrections on pixels at different depths of a captured image according to depth information. Background technique [0002] With the further development of information technology, especially the development of portable electronic technology, the portable electronic equipment integrated with a camera has increased rapidly, satisfying the user's demand for taking diverse images anytime and anywhere.

Problems solved by technology

[0003] However, in the case of low illumination, the existing cameras generally use the supplementary light unit to supplement the light, so as to make up for the lack of ambient light, and expect to get better images

However, since the color temperature of the supplementary light unit is fixed, usually for the front subject, the supplementary light received by the supplementary light unit is 10% compared to the supplementary light received by the rear subject or background environment. There are obvious differences

However, most existing cameras estimate a unique color temperature value for the entire picture taken, and restore all the pixels in the picture based on this color temperature value, resulting in poor color temperature of the front and rear subjects and the environment in the image. The problem of balancing and restoring
